Signet-ring cell carcinoma of the appendix with ganglioneuromatosis: a case report

BACKGROUND: Primary cancer of the appendix, especially signet-ring cell carcinoma, is an uncommon disease, and it is rarely suspected before surgery. Diffuse intestinal ganglioneuromatosis that is not associated with neurofibromatosis-1 or multiple endocrine neoplasia 2b is also rare. The most frequ...

Sumario:BACKGROUND: Primary cancer of the appendix, especially signet-ring cell carcinoma, is an uncommon disease, and it is rarely suspected before surgery. Diffuse intestinal ganglioneuromatosis that is not associated with neurofibromatosis-1 or multiple endocrine neoplasia 2b is also rare. The most frequent symptoms caused by it are changes in bowel habits, abdominal pain, and occlusive episodes. CASE PRESENTATION: The patient was a 48-year-old woman who had a month-long history of chronic abdominal pain, fullness, constipation, and diarrhoea. Enhanced computed tomography showed a 100-mm irregular swelling in the appendix and thickening of the appendiceal wall with cystic dilatation. Based on a preoperative diagnosis of appendiceal cancer, the patient underwent laparoscopic ileocecal resection with D3 lymph node dissection. Pathological diagnosis revealed a signet-ring cell carcinoma of the appendix with ganglioneuromatosis. The patient completed four courses of capecitabine plus oxaliplatin (CAPEOX) as postoperative adjuvant chemotherapy, and 23-month postoperative outcome was noneventful without recurrence. CONCLUSION: We report a signet-ring cell carcinoma of the appendix that was detected early because of its presence with ganglioneuromatosis.
